Why it works: Shallot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 3,737 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Cucumber with Parsley Sauce
Ingredients
Directions
Cook the cucumber
Pare the cucumbers and place them in boiling water.
Cook for about 10 minutes, then drain well and cut into 1-inch thick slices.
Make the sauce
Heat the butter in a stewpan, add the sliced cucumber and shallot, and season with salt and pepper.
Toss over the fire for a few minutes, then add the white sauce.
Just before boiling, add the beaten egg and parsley, stir, and cook gently until the egg thickens.
Season to taste and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the main body of the dish, becoming tender when boiled and then warmed in the sauce.
- White sauce
- Provides a creamy, moist base that coats the cucumber slices.
- Egg
- Thickens the sauce as it cooks gently, giving it a smooth, body-rich texture.
- Butter
- Adds fat and richness, helping the cucumber and shallot soften and carry flavour.
The step that matters
Adding the egg. Egg thickens by gentle heat, and if the sauce boils after the egg goes in, the egg can curdle and turn grainy. Add it just before boiling and cook gently until it thickens.
